I have a friend who wants to make her own podcasts. She has an iphone and windows based computers. She is not very adept with technology, and doesn't have much money to spend, but I would love to point her in the right direction in terms of software and any hardware she would need to make these podcasts.

Specifically, she wants to make podcasts of her yoga classes (she owns her own yoga studio).

What software / hardware setup would you all recommend for the easiest, cheapest, and most user friendly way to make and publish her own podcasts?

Is there a resource for any of your recommended methods that I could pass her way?
